• Voltage ratings: 120V AC / 28V DC
• Mounting type: Through hole, right angle, vertical orientation
• Actuator type: Round plunger
• Termination style: PC pin
• Operating temperature range: -30°C to 65°C
• Electrical life: 60,000 cycles
• Moisture sensitivity level: 1 (Unlimited)

The U811SD9AV2RE meets all specified parameters and is classified as an active product within the same C&K 8020 series, making it a direct functional equivalent suitable for replacement in applications requiring the U811SD9AV2LE.

Parameter Comparison

Engineering Selection Recommendations

The U811SD9AV2RE is the direct equivalent for the obsolete U811SD9AV2LE. Both components share identical electrical specifications, mechanical configuration, and environmental operating parameters. The U811SD9AV2RE carries active product status, ensuring ongoing availability and supply chain support. Both parts maintain equivalent compliance certifications (RoHS and REACH), with the substitute part classified as REACH Affected while the original is REACH Unaffected; this distinction does not impact functional compatibility. Selection of the U811SD9AV2RE eliminates obsolescence risk while maintaining full electrical and mechanical interchangeability with existing designs.

Frequently Asked Questions (FAQ)

Q: Can the U811SD9AV2RE be used as a direct replacement for the U811SD9AV2LE?

A: Yes. Both parts are SPDT momentary pushbutton switches with identical electrical ratings (1A at 120V AC / 28V DC), mechanical configuration (through-hole, right-angle, vertical mounting), and operating parameters (-30°C to 65°C, 60,000 cycle electrical life). The U811SD9AV2RE is the active equivalent.

Q: What is the primary reason to transition from U811SD9AV2LE to U811SD9AV2RE?
